An IP address is a unique number consisting of 4 parts separated by dots (eg: 217.247.84.89) associated with every system connected to a network. It serves as an identifier for devices on a network, allowing them to communicate with each other. Each device connected to the internet is assigned a unique IP address, which is used to route data packets between devices.

The correct answer is 1024KB because in the binary system, 1 kilobyte (KB) is equal to 1024 bytes. Therefore, one megabyte (MB) would be equal to 1024 kilobytes.

The correct answer is that the device is used to store large amounts of data in a computer system, and the data is retained on this device even when the computer is turned off. This suggests that the device being referred to is a type of non-volatile storage, such as a hard disk drive or solid-state drive, which can store data even without power. This type of storage is commonly used in computers to store files, programs, and other data that need to be accessed even after the computer is shut down.

The US Department of Defense is credited with inventing the internet. In the late 1960s, the Defense Advanced Research Projects Agency (DARPA), a division of the Department of Defense, developed the Advanced Research Projects Agency Network (ARPANET), which laid the foundation for the modern internet. ARPANET was a network of computers that allowed for the exchange of information between different research institutions. Over time, ARPANET evolved into the internet we know today, with the Department of Defense playing a crucial role in its development and expansion.

The keyboard is an input device, not an output device. It is used to input data into a computer system by typing on the keys. Output devices, on the other hand, are used to display or produce information from the computer system, such as printers which produce hard copies of documents, monitors which display visual output, and modems which transmit data over a network.

The correct answer is untitled.jpg, untitled.bmp, and untitled.tiff because these file extensions (.jpg, .bmp, .tiff) are commonly used for graphics files. The other file extensions (.nfo, .ogg) are not typically associated with graphics files.

Megabits per second is the correct answer because it is a unit of measurement commonly used to quantify the speed of data transfer over a network. Megabits per second represents the number of million bits that can be transmitted in one second, indicating the network's capacity to transmit data. Megabytes, bits, and megahertz are not specifically used to measure network speed, making them incorrect choices.

Bandwidth refers to the measurement of how much information can be carried over a wired or wireless communications link in a given time period, typically a second.
